Phoronix: F2FS Brings Per-File Encryption With Linux 4.2

Based on the native encryption support added to EXT4 with the Linux 4.1 kernel, Linux 4.2 is bringing encryption support to the F2FS file-system...

What's the advantages of this approach over something like LUKS?

Samsung makes a filesystem with TRIM improvements, and almost all of their own SSD's to do it so wrong you need to turn it off. Nice irony.

The advantages are many. Particularly, you can enforce access control to files using different keys. Full-disk encryption (like with LUKS) protects the entire volume, but while it's offline.

What's the advantages of this approach over something like LUKS?

One advantage is that you can use it transparently to securely store files on file synchronisation services (a.k.a. "in the cloud").

I.e. you are locally working with the mounted and unencrypted files, the file sync service, on the other hand, works with the raw and encrypted files.

It is more or less the only way to get both fast sync (only modified files get synched) and privacy (the sync never sees the clear text files).

Sounds very cool! Wish XFS could do something like this.
